Skinner Inc., in Boston, is auctioning the trophy on June 7, with an estimate of $60,000 to $80,000, at an American furniture and decorative arts sale, where it's rather improbably grouped with hooked rugs, whale teeth, hickory chairs and ventriloquist dummies' heads.
Haunted pier, joke shop, rock dummies, head-in-a-hole boards that are problematic by 2018 standards, that sort of thing.
After a few minutes, a man wearing work clothes and a cap will appear and begin whispering into the dummy head's ears.
Measurements were taken through dual microphones at ear entrances of a dummy head.
Different kinds of railway noise were measured through binaural microphones of a dummy head.
It has also shown that optimum helmet parameters depend on the mechanical properties of the dummy head used.
The speech was played through a loudspeaker located at 0° azimuth relative to the dummy head.
However, it requires a very specific recording setup using high-fidelity microphones mounted in a dummy head.
A further investigation is carried out, via simulation, to verify the shock absorption capacity of the PCJ with a dummy head obstacle.
The notion of HRTF remains the same if we replace the human head by a dummy head and the ears by two microphones.
A new dummy head, developed in a previous study and capable of simulating the relative brain skull displacement was used in the parametric study of the helmet to optimize the density of the polystyrene liner.
